It is a post mill built on a stone socle. What makes it essentially different from the other three post mills exhibited in the Museum is its system of harnessing the power of the wind. Instead of using vanes made of boards, this mill uses twelve sail arms made of triangular cloth.The triangular sails are fastened to solid whips. Only four of the twelve whips are attached to the wooden framework that goes through the end of the driving shaft.The remaining eight are attached by means of an iron collar. A mast about three meters long lengthens the driving shaft. Attached to its tip are the cables that hold each whip fast. The whips are also linked together by a cable. The rectangular building of the mill is placed on a stone socle. The square socle is built here, however, with stone masonry, which strengthens the central pivot. The building houses a single grinding installation. There is an open balcony on the backside of the building, on which a horizontal winch for hoisting the grain sacks is mounted.
